Answer:
x = (c+a)/2
y = (c-a)/2
Step-by-step explanation:
x+y=c
x-y=a
Add together to eliminate y
x+y=c
x-y=a
--------------
2x = c+a
Divide by 2
2x/2 =(c+a)/2
x = (c+a)/2
Multiply the second equation by -1
-x+y =-a
Add the first equation
x+y =c
-x+y=-a
-----------------
2y = c-a
Divide by 2
2y/2= (c-a)/2
y = (c-a)/2
Answer:
7 1/24
Step-by-step explanation:
First, you have to get the fractions to have the same denominator. So, you take 2/3 and 3/8 and find the smallest number by multiplying for the denominator. That number is 24 because 3 times 8 is 24 and 8 times 3 is 24.
Then, you multiply both the denominator and the numerator by the number that you got for the fractions. 2 * 8 = 16 3 * 8 = 24. 3 * 3 = 9 8 * 3 = 24. So, that gives you 16/24 and 9/24. Now since they have the same denominator you can add them.
This gives you 25/24 which equals 1 1/24.
Next, you can add the whole numbers. That is 6.
Lastly, take your fraction answer and your whole number answer and you get 7 1/24.
